In-App Purchasing

The In-App Purchasing (IAP) API makes it easy for you to offer digital content and subscriptions for purchase within your app, such as in-game currency, expansion packs, upgrades, magazine issues, consumables, and more. You can quickly be up and running, ready to give millions of Amazon customers the ability to purchase engaging digital content using Amazon 1-Click settings.

In-App Purchasing handles the details of purchase flow, payment processing, receipts, and rights management for the purchasable content. With unique receipt identifiers, the IAP API enables you to easily ensure that customers receive purchased in-app items quickly, as well as track transactions and fulfillment.

Amazon WebView API

By targeting the Fire OS platform, Cordova developers can create hybrid web apps that take advantage of the advanced web engine integrated into Fire devices.

Amazon WebView API (AWV) is a Chromium-derived web runtime exclusive to Fire OS. A drop-in replacement for the WebView that comes with Android devices, AWV makes it possible to create better performing and more powerful hybrid web apps by providing support for a faster JavaScript engine (V8), remote debugging, and hardware optimizations for Fire devices including an accelerated 2D Canvas, and access to HTML5 features not supported by Android’s built in WebView such as: CSS Calc, Form Validation, getUserMedia, IndexedDB, Web Workers, WebSockets and WebGL.

Amazon Fire TV, including both the Fire TV and Fire TV Stick, now support HTML5 web apps using the Amazon WebView. The Web App Starter Kit for Fire TV is a new open source project intended to help Cordova developers get up to speed quickly to creating a simple media-oriented app for this exciting new web platform. Features of the project include an example user interface designed for the 10 foot user experience, support for the Fire TV remote control, and sample components developers can include in their Cordova project to create a robust media app using HTML5 technologies.
